X Joseph S. NYE, JR.
These men’s names are arranged so that their family names are in larger type on the second line. Or, at least that’s the intention. But the man in the middle does not have a family name of “S. Nye, Jr.”!
His family name is “Nye”. “S.” is the first letter of his middle name, Samuel — his “middle initial” — and should be on the first line, after “Joseph”. “Jr.” (which means “junior” — in other words, his father’s name was also “Joseph S. Nye”) should be after the family name, but in smaller type, since it is not part of the family name.
O Joseph S. NYE, Jr.
